COMBINED LUNCH CARRIERAND HEATER.

Specification of Letters Patent.

Patented Aug. 4, 1914.

Application filed September 8, 1913. Serial No. 788,735.

To all whom it may concern Be it known that I, ALFRED Gr. Nomusnn, acitizen of the United States, and resident of Harrisburg, in the countyof Dauphin and State of Pennsylvania, have invented certain new anduseful Improvements in Combined Lunch Carriers and Heaters; and I dohereby declare the following to be a full, clear, and exact descriptionof the same,

reference being bad to the accompanying drawings, forming part of thisspecification, and to the figures and letters of reference markedthereon.

This invention relates to that class of domestic appliances adapted forholding food products, and particularly when prepared in the form ofedibles to be consumed away from home, and adapted for heating the foodproducts in a convenient and ready manner before the same are consumed.

. The object of the invention is to provide a simple and convenientdevice which will resemble closely an ordinary receptacle in which foodproducts for luncheon are carried and protected from contaminatinginfluences, but which embodies a convenient arrangement of heatingdevice so connected and associated therewith that its presence will notbe apparent and it will in no wise interfere with the ordinary handlingand manipulation of the container, and if desired may remain in placewhile the receptacle is being washed or cleaned.

The invention consists in certain novel details of construction andcombinations and arrangements of parts, all as will be hereinafterdescribed and pointed out particularly in the appended claims.

Referring to the accompanying drawings,Figure 1 is a perspective view ofthe lunch carrier and heater embodying the present improvements. Fig. 2is a similar view with the parts in the position to which they are movedwhen the heater is to be used for the purpose for which it is intended.Fig. 3 is a section in a vertical plane, showing the construction andrelation of the parts.

Like letters of reference in the several figures indicate the sameparts.

The containing vessel may be of any ordinary or preferred kind, that isto say, adapted for the reception of liquid or solid food products, butpreferably embodies a bottom cylindrical portion indicated by therefer-. ence letter A in the accompanying drawing, a top or closure B,and a suitable handle such as C, whereby the vessel may be transportedand handled either in carrying it from place to place or in using thereceptacle after the manner of a cup or drinking vessel.

The bottom a of the receptacle is preferably flat or provided with asmooth portion for a )urposc to be presently explained, and centrz ly itis perforated and provided with an upwardly extending socket F which maybe internally threaded at the lower portion, or, as shown, it may havesecured within it by solder or otherwise a threaded nut or sleeve fadapted for the reception of and cooperation with a threaded stem Gwhich projects upwardly from a sub-base adapted to form the body of alamp or heater which may thus be rotated to any desired position ofadjustment with relation to the body of the container.

In the preferred construction the subbase has a cylindrical peripheralwall G ornamented by suitable beading as shown, and the peripheral wallextends upwardly above the top of the body of the lamp and is of adiameter to receive the lower end of the cylindrical portion of the bodyof the receptacle. The top G of the lamp or subbase forms an annularseat or ring against which the plane edge of the bottom of the containerwill seat, so as to effect a tight closure of the lamp body when it isout of operation, the closure being of such character that it may bemade very tight due to the screw action of the stem connecting theparts. The body of the lamp is adapted to contain an absorbent materialsuch, for example, as wick asbestos, which is usually retained thereinby a gauze covering H, extending across the central opening of theannular top of the lamp body.

The screw stem may, of course, be secured within the lamp body in anysuitable mannor, as by soldering or otherwise, the prime object being tomake a rigid connection whereby, when the parts are separated to theposition shown in Fig. 2, the container will be supported firmly and thelamp may be left lighted, even though the container is being used forthe time being as a drinking cup or receptacle from which the contentsmay be discharged by tipping the receptacle.

f course, alcohol or other liquid fuel is to be placed in the lamp bodyand the receptacle is to be screwed down tightly thereon when the lampis not in use, so as to prevent any evaporation or loss of the fuel andthe screwing down of the receptacle will act as,

an extinguisher if the lamp is lighted.

By the employment of a relatively small central screw threaded stem theturning of the receptacle and lamp body with respect to each other so asto adjust them nearer to or farther from each other is comparativelyeasy, and there is little or no danger of the parts becoming stuck orinoperative. Furthermore, this construction avoids the necessity ofemploying any supporting standards around the lower edge of thereceptacle, where the same would be subjected to heat and blackeningflame, and thus insures a long life for the device as a whole.

When the container or receptacle and lamp are brought together, as shownin Fig. 1, the receptacle presents practically the appearance of areceptacle having no heating attachment, there being no externalprojections or parts to catch or be broken or destroyed by rough usage.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent of the United States, is:

1. In a combined lunch carrier and. heater, the combination with thecontainer having a cylindrical body, closure and handle, and a centralscrew threaded socket in the bottom, opening downwardly, of a lamp bodyhaving a cylindrical wall adapted to receive the lower portion of thecontainer, an annular top against which the bottom of the containerseats to form a closure for the lamp bodywhen not in use as a lamp, anda cen tral screw threaded stem rigidly mounted in the lamp body andextending into the socket in the bottom of the container for adjustablyconnecting the parts with each other.

2. A combined lunch carrier and heater comprising in combination acontainer having a cylindrical body and a central screw threaded socketin the bottom, a lamp body having a cylindrical wall and annular topadapted to receive and seat the lower portion and bottom of thecontainer, and a screw threaded stem rigidly mounted in the lamp bodyengaging the screw threaded socket for adjustably connecting the partsto support the container above the lamp when burning and to'extinguishthe lamp and seat the container when screwed home to prevent loss byevaporation of the fuel.
